Further, when droping to ground, the ground detection switch Guan Bi of this testing circuit makes this MCU microprocessor eventually
Only automatically control and record this fall time of T.
Further, if the level detection switch Guan Bi of this testing circuit, think that this flying toy drops to the water surface, this
Time this MCU microprocessor records T fall time start auto-returned program, first control this flying toy rise time T, so
After derive data this flying toy of Reverse Turning Control from this memorizer, to ensure that flying toy returns safe landing point.
Further, during auto-returned, this control circuit allows to receive remote command to ensure more preferably to return
Safe landing point.
Further, if not receiving remote command or carrier information for a long time behind this flying toy landing ground, think
This flying toy is in beyond this remote controller span of control or this remote controller damages, and this flying toy sends some with certain frequency
Secondary sound and light alarm, and after certain time, then start auto-returned program, first this MCU microprocessor controls on this flying toy
Rise time T, from this memorizer, then derive data Reverse Turning Control flying toy, to ensure that flying toy returns safe landing
Point.
Further, during auto-returned, this control circuit allows to receive remote command to ensure more preferably to return
Safe landing point.
Further, when after this remote controller power down, this flying toy can't detect instruction or carrier only, this flying toy with
Certain frequency sends sound and light alarm, and when this flying toy power down, this MCU microprocessor utilizes the residual electricity on electric capacity should
The record of memorizer is deleted in order to avoid this flying toy mistake enters auto-returned program.
Compared with prior art, the present invention a kind of can the flying toy control circuit of auto-returned by MCU microprocessor
The valid instruction of record-setting flight toy and persistent period, and the fall time of record-setting flight toy, to detect in testing circuit
Land when the water surface, start auto-returned program, make flying toy return safe landing point, meanwhile, if landing ground after long time
Between do not receive remote command or carrier information, make flying toy send sound and light alarm several times with certain frequency, and start from
Dynamic return program, make flying toy return safe landing point, it is to avoid the accidental damage of flying toy.
Accompanying drawing explanation
Fig. 1 is that the present invention is a kind of can the circuit structure diagram of flying toy control circuit of auto-returned.
Detailed description of the invention
Below by way of specific instantiation accompanying drawings embodiments of the present invention, those skilled in the art can
Further advantage and effect of the present invention is understood easily by content disclosed in the present specification.The present invention also can be different by other
Instantiation implemented or applied, the every details in this specification also can based on different viewpoints and application, without departing substantially from
Various modification and change is carried out under the spirit of the present invention.
Fig. 1 is that the present invention is a kind of can the circuit structure diagram of flying toy control circuit of auto-returned.As it is shown in figure 1, this
Invent a kind of can the flying toy control circuit of auto-returned include decoding unit 10, MCU microprocessor 20, driver element 30,
